Description
Genuine Smokey Quartz Point from Madagascar – Natural Mineral Specimen
This Smokey Quartz Point from Madagascar is a completely natural mineral specimen chosen for its clarity, colour depth, and beautifully formed point termination. Each piece displays unique internal features, subtle colour zoning, and natural crystalline geometry that reflect the geological processes that shaped it. The photograph in the listing shows an example of the actual quality and type of specimen you will receive, with individual pieces ranging from 30–65mm in length. A 1cm scale cube is included in the images to help convey accurate size and proportions. All specimens are 100% genuine and include a Certificate of Authenticity, reaffirming their origin and authenticity.
Geological Formation – How Smokey Quartz Develops in Madagascar
Smokey Quartz forms deep within the Earth’s crust in silica-rich environments, often within pegmatites and hydrothermal veins where mineral-rich fluids cool slowly over long geological timescales. Madagascar is especially renowned for producing high-quality quartz due to its ancient crystalline bedrock and stable geological conditions. These environments facilitate the growth of large, well-defined quartz crystals with excellent transparency and distinctive smokey colouration.
The smokey hues result from natural radiation emitted by surrounding rocks over millions of years. When this radiation interacts with trace amounts of aluminium within the quartz lattice, it forms colour centres that give Smokey Quartz its characteristic brown, grey, or deep charcoal tones. This natural irradiation process is entirely geological, taking place over vast time periods and giving each piece a unique and authentic appearance.
Mineralogical Characteristics – Structure, Features, and Identification
Smokey Quartz is a member of the silicate mineral family, composed of silicon dioxide (SiO₂). It crystallises in the trigonal system, forming six-sided prisms that terminate in a pyramid-like point. Madagascan Smokey Quartz is known for its excellent clarity, refined structure, and rich colour, making it desirable among collectors and mineral enthusiasts.
Characteristic features of Smokey Quartz Points include:
- Natural point termination, either single or partial depending on growth conditions
- Colour range from pale translucent grey to deep smokey brown, created through natural irradiation
- Visible internal veils, phantoms, or zoning, offering insight into crystal growth history
- Hardness of 7 on the Mohs scale, providing excellent durability
- Distinct prismatic structure, common to all quartz varieties
These natural points often contain internal textures formed during growth, including ghost-like phantoms, fluid inclusions, and micro-fractures that catch the light and enhance the crystal’s visual appeal.
Scientific and Collectible Value
Smokey Quartz offers both aesthetic and geological significance. Its internal features act as a historical record of the conditions present during crystal formation, capturing the environmental changes, heat variations, and mineral interactions that occurred over millions of years. Collectors appreciate Madagascan Smokey Quartz for its combination of clarity, colour saturation, and natural point structure, as well as the geological history contained within each crystal.
Because these points form within stable pegmatitic and hydrothermal systems, they often develop well-defined terminations and consistent internal architecture. This makes them valuable for display, educational use, geological study, or as decorative natural mineral pieces.
Carefully Selected Natural Specimens with Certificate of Authenticity
Each Smokey Quartz Point is chosen for its quality, colour, natural structure, and overall visual presence. While the photograph shows a representative example, your piece will match the same high standard and fall within the 30–65mm size range. A 1cm scale cube provides accurate visual context in the images. Every specimen includes a Certificate of Authenticity, confirming it as a genuine natural mineral from Madagascar and ensuring its authenticity for collectors, enthusiasts, and gift buyers alike.
